hi, the seed works partially, and if you start a new game not over the menu, it will set a new one. so you need to write everytime you start a run go to the menu and write it down.
its influence what will be in the cup and when an event will come. the problem is, if you make in this run something different, like buying somthing or click on a different time on barbra, then the seed is allready in the background a bit different than before
